Abstract:
Described herein are methods and devices for use in telecommunication cell selection and re-selection for which there may be multiple different sizes of transmission bandwidth configurations in a telecommunications operating band. For each of a plurality of channel hypotheses, in which each channel hypothesis has a hypothetical occupied portion and a hypothetical guard band portion, a respective metric is calculated based on a power value for the hypothetical occupied portion and a power value for the hypothetical guard band portion. Based on the metrics determined for the plurality of channel hypotheses, at least one channel hypothesis is selected for further processing for cell selection or re-selection. The metric is calculated by determining a difference between the power value for the hypothetical occupied portion and the power value for the hypothetical guard band portion.
